This case study described a Staffordshire Bull Terrier diagnosed with alopecia by color dilution, characterized by gradual hair loss and confirmed through clinical examination and histopathology.

This study found that specific histologic features in skin biopsies can help support a diagnosis of traumatic alopecia (trichotillomania), but not all markers are distinct to the condition.

This study concludes that tiny infundibular cysts, rather than comedones, are the primary lesions in chloracne.

This study found that the absence of sebaceous glands may be an early factor in the development of keratosis pilaris, leading to hair shaft and skin barrier abnormalities, independent of filaggrin mutations.

Treatments for melanin disorders exist, but more effective options needed.

The authors observed that the patterned melanoderma on the hairless scalp of fair-skinned Caucasian men with androgenic alopecia resembled similar patterns seen on facial skin.

This abstract describes the role of melanin in determining hair color and protecting against UV radiation, highlighting how its production affects hair health, growth, and vitality, with reduced production contributing to greying with age.

This study found that microneedling combined with calcipotriol plus betamethasone was more effective in treating vitiligo than microneedling with tacrolimus, particularly in difficult-to-treat areas.

A synthetic drug and a South American herb may help treat alopecia areata in Chinese men.

This study found that in women with PCOS, suppressive therapy using spironolactone plus oral contraceptives improved hirsutism more effectively than either treatment alone, with initial scores predicting success.

This study found that treating a 3D hair dermal papilla model with rice bran extract and electromagnetic fields increased melanogenesis, suggesting potential for vitiligo and white hair therapies.

This article discusses how the balding scalp's exposure to UV and near-infrared light may accelerate aging, with changes detectable under ultraviolet light; it presents no new clinical findings.

This study found that extracellular ATP released from UVB-irradiated keratinocytes promotes melanin production through the P2X7 receptor, indicating a role for ATP-P2X7 signaling in UV-induced melanogenesis.

This study suggests that hair loss in Chesapeake Bay retrievers is a breed-specific syndrome characterized by unique histological features and abnormal steroid production, possibly influenced by familial factors.

This study found that rice bran ash extract enhanced melanin biosynthesis-related protein expression in a 3D hair follicle-like tissue model and hair follicle organ culture, suggesting potential for future research in melanogenesis.

This study assessed three materials—L-arginine, hydrolysed keratin, and cystine-silanol copolymer—ex vivo for their potential to reduce undesirable effects of hair bleaching, such as damage to hair proteins.

This symposium abstract reports no new experimental results and discusses the pathophysiology of hair growth as presented at an event organized by the Institute of Dermatology.

This study concluded that dermoscopy enhances the diagnostic capability for cicatricial alopecia beyond clinical inspection and identified novel dermoscopic features such as blue-grey dots.

This article discusses the complex biological functions and social significance of hair follicles and reports no new research findings, emphasizing their role in health, disease, and a substantial beauty industry.

In this review, researchers examined the current status and advancements in using long-pulse alexandrite lasers for treating hair removal, vascular lesions, and pigmented lesions, aiming to guide clinical use based on how the laser's 755nm wavelength is absorbed by melanin and hemoglobin.

Trichoscopy helps tell different hair loss types apart using specific scalp and hair patterns.

This study analyzed trichoscopic features of discoid lupus erythematosus on the scalp in skin of color and found distinct patterns based on clinical morphology.

This review explores the causes and mechanisms of alopecia areata and discusses current treatments, reporting no new clinical findings.

This study found that anagen-phase hair follicles in mice are particularly sensitive to damage by ruby laser pulses, resulting in alopecia without scarring, suggesting enhanced laser hair removal strategies.

This study reported that using condensed nanofat combined with fat grafts significantly improved the aesthetic and functional aspects of atrophic facial scars in 20 patients, as assessed by both patients and plastic surgeons using the Patient and Observer Scar Assessment Scale.

This study found that inhibiting PKC-β activity with bisindolylmaleimide reduces pigmentation in the skin and hair of guinea pigs and mice by preventing tyrosinase activation.

This study found that dual inhibition of BACE1 and BACE2 in mice affects melanosome maturation and causes dose-dependent hair depigmentation without altering retinal morphology.

This study found that murine skin is a target for melatonin bioregulation, as melatonin affected DNA synthesis and tyrosinase activity in skin organ culture.

Other common signs, not just the well-known immune cells around hair bulbs, are important for diagnosing hair loss from alopecia areata.

This article reviews drug-induced pigmentation and reports no new clinical findings, highlighting difficulty in confirming drug associations due to factors like delayed onset and polypharmacy.
